SaaS, PaaS and IaaS
Understanding SaaS, PaaS and IaaS
In an evolving landscape of cloud computing, understanding the different service models is critical for organisations aiming to enhance, develop, and grow their IT infrastructure.
Expertise in cloud migration and optimisation
Our IT lawyers are well placed to assist organisations with all aspects of SaaS, PaaS and IaaS, providing expert guidance and support to optimise their cloud infrastructure and services.
We are experienced in assisting with migration strategies, cost optimisation, and ensuring compliance with industry standards, enabling organisations to leverage the full potential of cloud-based technologies to drive innovation and growth.
Key legal considerations:
Software as a Service (SaaS) is a cloud computing model where software applications are delivered over the internet. Users can access these applications via a web browser, eliminating the need for local installation and maintenance. Common examples include:
- Data security and privacy:
Organisations should make sure that any commercial agreement includes obligations on the SaaS provider to comply with relevant data protection regulations, such as UK GDPR and the Data Protection Act 2018 - Service Level Agreements (SLAs)
A review of any proposed SLAs will be required in order for an organisation to understand the uptime guarantees, support response times, and penalties for non-compliance - Integration capabilities
Organisations should assess the ease of integrating any new SaaS application with its existing systems and workflows - Scalability
As a long-term consideration, organisations should assess the scalability potential provided by the SaaS vendor to accommodate any future business growth
Platform as a Service (PaaS) provides a cloud-based environment with tools to develop, test, and deploy applications. It includes infrastructure (servers, storage, and networking) and middleware (databases, development frameworks) that developers need to build applications.
- Development tools
Organisations should take care to ensure that the PaaS supports the programming languages and development frameworks used by its internal IT teams - Data management
Organisations should assess the PaaS provider’s data management capabilities. This includes data backup, recovery, and migration options on exit - Security
It is important for organisations to verify the level of security measures in place, in order to protect their data - Vendor lock-in
Organisations should be mindful of any long-term commitment or vendor lock-in. This includes undertaking an assessment of what steps may need to be taken to migrate any applications to another PaaS provider if needed
Infrastructure as a Service (IaaS) offers virtualised computing resources over the internet. It provides fundamental infrastructure such as virtual machines, storage, and networks, allowing organisations to build and manage their own IT environments without the need for physical hardware.
- Cost management
Organisations should take steps to understand the pricing model and monitor ongoing usage in order to manage costs - Performance and reliability
Organisations should undertake proper due diligence to fully evaluate the performance and reliability of the proposed IaaS provider - Compliance
- Ensuring that the IaaS provider complies with industry standards and all applicable law and regulations relevant to an organisations business will be key to mitigate any compliance-related issues
- Service levels and disaster recovery
Organisations will need to assess the appropriateness of any agreed Service Levels the disaster recovery options and ensure that in the event of an outage, the organisation’s data and any applications can be restored in a timely and efficient manner
